SYNGAS COMBUSTION CHARACTERISTICS OF OXYGEN CARRIER PARTICLES IN A BATCH FLUIDIZED REACTOR
Introduction Chemical-looping combustion (CLC) is a novel combustion technology with inherent separation of the greenhouse gas CO2 and no Nox emission. The previous results on chemical-looping combustion technology have concentrated on improvement of the oxygen carrier particles and most of the studies used methane or hydrogen as a reduction gas 1. In order to understand the performance and the feasibility of the chemical-looping combustion system, it is necessary to check the performance of the oxygen carrier particles by using gaseous fuel such as natural gas and syngas.Moreover, confirmation of reduction of Nox emission in the oxidizer and high CO2 selectivity in the reducer are prerequisite for application of the chemical-looping combustion system in commercial plants. Natural gas has been considered as a major fuel in the chemical-looping combustor so far. However, syngas has lately attracted considerable attention as a fuel can substitute for natural gas in the chemical-looping combustor because of high oil price.However, there is a lack of experimental data on syngas-fueled chemical-looping combustion. Mattison et al. 2 used a TGA and a batch fluidized bed for reaction tests, but the effect of temperature on the product gas distribution was provided only for CO concentration.Johansson et al. 3 used a fluidized bed reactor, and they reported the product gas distribution, but did not measure the Nox concentration during, oxidation.
